Polymer-coated urea won the Guinness World Records in 2012&lpar; Slow Release Fertilizer with the highest content of Nitrogen in the word--N 45&period;6&percnt;&rpar;&period;

Shandong Agricultural University Fertilizer Science & Technology Co&period;&comma; Ltd&period; Developed the high-tech products---polymer coated urea&comma; which has the independent intellectual property rights&comma; according to the fifth generation of ultra-super thin film coating technology&period; The products with good controlled release effect&comma; has been tested by domestic and foreign research institutes&comma; colleges and universities and agricultural extension departments&period; The content of Nitrogen&comma; The initial release rate&comma; and The cumulative nutrient release have been approved by Guinness World Records&period;The unique advanced production technology of PCU&comma; which totally controlled by DCS central system&comma; is the most automated and maximum single productivity&period; The product quality is superior to the national standard&comma; because of the uniform particles&comma; stable quality&comma; the highest N content&comma; the thinnest coating&comma; easily degradable and longest release period&period;

B&colon; Higher Nitrogen content and Longer release longevityThe thin&comma; durable and consistent coating makes the product higher nitrogen content&comma; And the PCU is good for producing kinds of BB fertilizers for different crops&period; The long-lasting release and release rate is correspond to the ertilizer-required rhythm&comma; providing a continuous and controlled supply of nitrogen for the period while of nutritional needs&comma; avoiding burning seedlings or shorting of fertilizer&period;

C&colon; Environmentally FriendlyProduction process without solvent &comma; the use of links reduce the amount of fertilizer&comma; can reduce nitrogen loss&comma; less volatile&comma; leaching &comma; reducing the accumulation of nitrogen in the soil&comma; reducing its salinity significantly improve the degree&comma; fertilizer saving&comma; fertilizer use efficiency&period; The producing process of PCU is clean&comma; non-toxic&comma; non-waste&comma; without pollution&comma; zero emissions and the coating degrades naturally and safe in time&period; It was solvent-free in the processing line&period; The less fertilizer and high utilization rate can reduce tRhe volatilization&comma; leaching loss of nitrogen&comma; reducing the accumulation of nitrogen in the soil&comma; and its extent of salinization&period; Released completely&comma; the coating will degrade gradually&comma; leaving no residues in the soil&period;

D&colon; High efficient and economicalFertilizer only once during the whole growing season&comma; which help us to save the labor&comma; time and cost&period;
